What it is
A monopolar RF platform combining 6.78 MHz and 2 MHz with selectable depth modes and surface cooling.
Dual-frequency RF can be delivered across selectable depth modes while impedance feedback and cryogen cooling help manage energy delivery.
Who it may suit
Adults discussing mild-to-moderate laxity, facial contour or skin-firmness concerns without surgery.
Who needs extra review
People with an active skin infection, certain implants or devices, or goals that require surgery need an individual medical assessment.
